When Windows Live Messenger's "i'm Making a Difference" challenge was first announced, Microsoft said it would award a dollar for every member to the winning non-profit organization (the maximum donation sum being $50,000). The group's member numbers surged quickly - there are 62,795 members at the time of this newspost - allowing the software giant to make the full donation. After grabbing the most votes, the Humane Society of the United States is receiving the $50,000 donation from Windows Live on behalf of the Facebook group and its members.

"The Humane Society has been working since 1954 to celebrate animals and confront cruelty in all its forms. It's the nation's largest and most powerful animal protection organization, working tirelessly to advocate for a population unable to advocate for itself. We hope this contribution helps them continue their vital work. To everyone that joined the group: Thank you! Thank you for joining, thank you for telling your friends, and thank you all for speaking out passionately on the wall and the message boards. Together, we are truly making a difference!" read a note on the Facebook group's page.
